First of all, good ICO should have a big and experienced team. Their also product is very important because they should offer a solution to a problem or can be used by many people. You may follow some experts or bitcointalk members to find good ICO but you should make own research.
Yes I strongly agree on that , if we are going to choose an ICO we must see the experience of the team and it's past success because there are so many scam ico on the feild and we can be possibly being victimized by them of we are not careful to choose. I believe that if we choose the experience team we can possibly also choose the amazing ico.
